Divide the oscillator by 10^7 to generate a 1 pulse per second output.
You might be able to tell your frequency counter to measure with a
1 second gate time and take out a gate signal, if the counter provides
it (or add your own).

Compare the phase of this to WWV by recording both with a PC sound
card for 24 hours.  Adjust it until it holds 1/10 of second per day
which is 1 ppm.
